1500 to 2000 rpms my 5.0 h.o bogs down and then it will get past 2000 rpm and clear up. did complete tune up. timing at 15 everything. i am pretty sure a vacuum somewhere is leaking to cause when it revs down it will sit just about my idle then bout 5 second later it will rest at idle. help please.
